• Signal Test can place marks on the map while a test is running, so you can see where contact was made. • Finished tests stay on your phone. Open one to review the path on the map, including the ground between points. Swipe a saved test to delete it. • When another phone starts a signal test, you get a notice and its marks appear on your map. When that test stops, you are notified.

• The full NATO alphabet is available as a callsign, with each name shown in your language. A station already chosen by someone else is dimmed and marked In use. • Your selected callsign and team color now match on the other phones, including the color under the name. If no callsign is set, the radio name is shown instead. • Map warnings reach the other phones, including when the map is already open. • Circles keep their real size on the map. • A thin queue bar above the map mode label shows how many messages are still waiting to send. • Signal Test can keep running while you leave Settings, and its loss stats stay visible. Start stays off until a node is connected. • The connected device card is clearer, and Bluetooth messages are shown in your language.

• Signal Test now tracks outbound probes by mesh ACK, with clearer sent and received miss rates • Signal Test keeps running when you leave Settings; a map banner opens the test so you can stop it anytime • Clear log no longer stops an active Signal Test • Start stays disabled until a MeshGrid node is connected • Devices screen: connected node shows a simple centered name, icon, and Disconnect control • BLE connection errors on Devices are localized • Fresher advertised device names; forgetting a node in iPhone Bluetooth clears the saved MeshGrid link • Map battery indicator hides until the node reports a real level • Reliability and localization improvements

• New Stats screen under Preferences: see Bluetooth upload and download totals for this phone and your MeshGrid node, with automatic B / KB / MB / GB units and a reset option • Stability improvements

• Chat delivery receipts: your outbound messages show a green check when a mesh peer acknowledges receipt • More reliable delivery status tracking between the app and your node • Stability improvements

• Earthquake layer now shows tectonic plate boundaries and active fault traces as red lines on the map • More reliable firmware update detection when a required build is listed in the release title • Stability and build fixes for the latest Xcode toolchain

Map & identity • Your callsign stays locked under the blue puck while you move. • Fewer duplicate markers when your radio short name and callsign both appear on the mesh. • Peer callsign labels keep a solid black badge (no more missing background). • Chat shows the mesh node name when a sender has no callsign. Emergency locations • Rapid emergency sends now pair GPS with each message more reliably, so more alerts show on the map cluster, not only in chat. • Mesh chat receive and send start with the app, so messages are less likely to stall if the map loads slowly. Firmware • Firmware update checks use the MeshGrid-Node GitHub releases page. • Clear yellow notice when your node BUILD is behind the published requirement. • More reliable reading of the node firmware version over Bluetooth.

Map & position * Your callsign sits in a black badge directly under the blue puck and stays aligned while you move. * If you set a callsign it is used on the map and in mesh traffic; if not, your connected mesh node name is shown instead of a generic “Node …” label. * Fewer duplicate dots at your position when the radio short name (e.g. ALPHA) and your callsign both appear on the mesh. * Peer callsign labels use the same solid badge style so the black background does not disappear after style reloads. Emergency & chat * Emergency codes link more reliably between chat and map (“Show on map”, GPS pairing for rapid sends). * Routine location reports no longer crowd out emergency mesh traffic. * An emergency is handed to the radio only after both the message and GPS row are saved. * Incoming chat shows the mesh node name when the sender has no callsign. Hazard alerts * Received hazard alerts appear on the map and in a list near the map controls. * Tap an alert to focus it on the map; fire, flood, and earthquake use distinct markers. * Foreground notifications; earthquake pushes respect your magnitude setting in Notifications. * Swipe to delete an alert; clear all with confirmation in every supported language. * Unread hazard count on the app icon; bell badge clears when you open the list. * Alert language updates when you change app language. * Hazard device secret stays on this device only. Shapes & messaging * Outgoing chat messages show send progress under the bubble. * Drawn shapes show pending or failed sync on the layer that owns them, with retry after restart where applicable. Security & reliability * When BLE encryption is on, unencrypted node notifies are rejected. * Safer handling of saved passwords and keychain errors (missing vs failed read). * First Aid answers stay grounded in bundled content; weak matches do not invent medical text. * Fixes so failed saves or loads do not look like an empty chat or empty lists. * HUD weather/overlay fetch steps time out cleanly instead of stalling the queue. * Improved crash and hang reporting to help fix stability issues (no chat text or coordinates in reports). * Privacy manifest and declared data use for App Store requirements. Other * Message notification sound plays without blocking the UI. * Earthquake feed combines USGS and EMSC with periodic refresh (where enabled in your build).

Hazard alerts now warn you about nearby earthquakes, wildfires, and floods in your selected language. Set the distance and the minimum earthquake magnitude in Notifications. Open an alert to see it on the map. Earthquakes, fires, and floods use their own icons. A bell next to the map view button lists alerts you have received. Tap one to go there. Swipe to delete, or clear the list. The bell and the app icon show how many you have not opened. The earthquake layer now combines USGS and EMSC reports and refreshes more often. Hiking trails are colored by source. Opening the map no longer crashes on launch.

OFFLINE-FRIENDLY MAP HUD When you enable HUD weather and hazard layers, MeshGrid saves the latest data after a successful online fetch. If you lose signal, layers you already loaded can remain on the map instead of disappearing immediately. HIKING TRAILS Turn on the trails layer to see marked hiking routes and supplementary path geometry from MapTiler and OpenStreetMap US. Control the layer from the bottom-left map HUD or Settings → Map. MAP AND RELIABILITY • More reliable overlay loading and disk caching for ocean currents and other HUD data • Updated layer markers for earthquakes, fires, fog, and pressure • Better handling of background fetch and battery use while layers refresh • Compass and device orientation updates for current iOS releases • General stability improvements and Swift 6 compatibility fixes

Map layers & HUD • Redesigned bottom-left map layer menu with a fixed order so toggling layers no longer jumps rows around. • Air quality (AQI) is first in the stack, with high-contrast on-map markers (icon + value). • Pressure, visibility (fog), active fires, and earthquakes use clearer, tappable map markers; very close fire hotspots cluster with a count badge. • Hiking trails use a brighter, easier-to-see line style on the map. • When the device is offline, network-based map layers and the layer HUD are hidden; they return when you are back online. • Turning on another layer while two or more are active shows a short battery tip at the top of the screen. Ocean, weather & SAR • Improved ocean current animation and time scrubbing on the map HUD. • SAR drift "possible location" follows ocean currents over time and is easier to see on open water. • Wind and related weather grid overlays remain smoother during map use. Mesh & devices • Improved background Bluetooth reconnect to your saved MeshGrid device without opening Devices first. • Discovery behavior adjusted when no saved device is paired. Reliability & performance • Faster, more stable app startup and map loading. • Map drawing and layer update fixes. Localization • New and updated strings for map layers and HUD across all supported languages.

This update strengthens MeshGrid's core performance infrastructure. We've optimized data processing to deliver a much smoother map experience and uninterrupted messaging. With background memory management improvements and critical bug fixes, we have maximized the app's stability and reliability for your essential field operations. We've also improved how mesh chat emergencies work on the map. When someone sends an emergency with a location, you'll see a clear red marker and short label on the map so the situation is easy to spot in the field. The map keeps the latest emergency per person, yours and each peer's, at the right coordinates, while full history stays in chat. You can remove a pin from the map from Layers when you no longer need it on screen, without deleting the message. Everything is rebuilt from your saved chat when you reopen the app, so pins stay consistent as long as the messages remain.
